Electroylsis- The Basics
- When you want to break an ionic compound with electric current, this is called Electrolysis.
- It has to be molten or a solution.
- Electrons are taken from ions at a positive electrode (anode) and a negative electrode (cathode).
Example- Lead Bromide
As Lead is positive it goes to the negative electrode (Cathode) and Bromine is negative to it goes to the positive electrode (Cathode). There are half-equations that go with this:
Pb2+ + 2e- = Pb
2Br = Br2 + 2e-
There are another two elements if you cannot…
